What are the main differents between a light microscope and an elecron microscope?
Both use an electromagnetic beam to examine objects but as the names suggest one uses a beam of light whilst the other uses electrons. The resolution of a microscope is limited by the wavelength of the beam used. The smaller the wavelength used the smaller the objects that can be resolved. This is similar in principle to the clarity of a digital picture. The more pixels used in the original picture (corresponding to a smaller wavelength) the more it can be enlarged without losing definition.
